php簡單實作多語言切換的方法_php技巧

本文實例講述了php簡單實作多語言切換的方法。分享給大家參考，具體如下：

1.主程式碼：

<?php
include "lib/function.php";
?>
<script src="js/language.js"></script>
<?php
if(isset($_get["language"])){
  $_session["language"] = $_get["language"];
}else{
  $_session["language"] = getdefalutlanguage();
}
$language_name = getlanguagename($_session["language"]);
include "lang/".$language_name.".inc";
?>
<select name="language" id="language" onchange="changelanguage(this)">
<?php
  $language_array = array_language();
  foreach($language_array as $key => $value){
    if($_session["language"] == $value){
      $selected = "selected = 'selected' ";
    }else{
      $selected = "";
    }
?>
<option value="<?php echo $value;?>" <?php echo $selected;?>><?php echo getlanguagename($value);?></option>;
<?
  }
?>
</select>
<?php
  if($_get["language"] == $value){
      //$selected = "selected = 'selected' ";
    }
echo "语言：".$_session["language"];
